Abstract
The invention discloses a super-lubricating water-based cutting fluid and a preparation method thereof, wherein an aqueous dispersion liquid obtained by dispersing hard inorganic matters with Mohs hardness of more than 8 by adopting a fatty alcohol polyoxyethylene ether modified phosphate dispersant is used as a lubricating component. The fatty alcohol polyoxyethylene ether modified phosphate dispersing agent has a strong chemical adsorption effect with the surface of metal or alloy, and can quickly drive hard inorganic particles to migrate to the surface of a processing part in the cutting processing process. The nano-scale hard inorganic particles play a role of a rolling bearing between a cutter and a workpiece in the cutting process, so that the friction resistance in cutting can be obviously reduced. The chemical adsorption effect of the fatty alcohol polyoxyethylene ether modified phosphate dispersant and the rolling bearing effect of the nanometer hard inorganic particles are comprehensively utilized, and excellent lubricating characteristics are obtained.
Description
Technical Field
The invention belongs to the field of metal cutting and lubrication, and particularly relates to a super-lubrication water-based cutting fluid and a preparation method thereof.
Background
The metal cutting fluid (cutting fluid) is used in the cutting, grinding and other processes of metal and its alloy, and has the functions of cooling and lubricating cutter. Cutting fluids can be classified into oil-based cutting fluids and water-based cutting fluids according to their main components. The oil-based cutting fluid mainly comprises mineral oil, an oiliness agent and an additive, has excellent lubricity and rust resistance, but has larger cooling performance, is not easy to clean and dilute, has great environmental pollution, and is limited to be used due to the defects of low flash point, flammability, small heat conductivity coefficient and the like in certain fields with fire hazard and explosion danger and the need of rapid heat dissipation. The water-based cutting fluid is mainly prepared by mixing alcohol amine or alcohol ester with deionized water, and adding various additives such as defoamer, antirust agent, dispersant, stabilizer, extreme pressure resistant agent, polishing agent and the like, and has good heat conductivity and cooling property, but has poor lubricity, complex components, serious environmental pollution caused by the additives and high cost caused by more components.
In order to improve the lubricity of water-based lubricants, various types of surfactants have been developed for use in formulation systems in combination with oily liquids such as vegetable oils, mineral oils, oleic acids, and the like. Patent CN103589489a discloses an environmentally friendly aqueous lubricant comprising coconut oil, borax, sodium cumene sulfonate, rust inhibitor and water, wherein the coconut oil and sodium cumene sulfonate act as lubrication. Patent CN1321734a discloses an antirust antibacterial water-based cutting fluid, which is prepared from mechanical oil, oleic acid, alkenyl succinic acid, alcohol amine, surfactant, phosphorothioate, sodium nitrite and sodium benzoate, wherein the surfactant is a mixture of polyethylene glycol and O pi series surfactant or T80 surfactant. The formula comprises a plurality of lubricating components such as mechanical oil, oleic acid, alcohol amine, phosphorothioate, surfactant and the like. Patent CN113403131a discloses a proton type ionic liquid which can reduce the shearing force of cutting fluid, thereby realizing super lubrication performance. The proton type ionic liquid is oily liquid prepared by long-time reaction of phosphate and alkylamine with equal mass in acetonitrile solvent. It can be seen that most of the current means for improving the lubricating performance of the water-based cutting fluid are combinations of various functional auxiliary agents with surface activity, even just stacking, and the obtained effect is limited, so that the cost of the product is greatly increased, and the improvement of the lubricating performance of the water-based cutting fluid is still a great difficulty in the field.
Disclosure of Invention
The invention aims to provide a super-lubricating water-based cutting fluid, which is endowed with super-lubricating property by combining a chemical adsorption mechanism with a physical bearing lubricating effect.
Still another object of the present invention is: a preparation method of the super-lubricating water-based cutting fluid is provided.
The invention aims at realizing the following scheme: the super-lubricating water-based cutting fluid consists of the following components in parts by weight:
24.0 to 80.0 parts by weight of super lubricant;
5.0 to 10.0 parts by weight of humectant;
0.5 to 2.0 parts by weight of bactericide;
1.0 to 5.0 parts by weight of rust inhibitor; and
3.0 To 69.5 parts by weight of deionized water,
The super lubricant is an aqueous dispersion prepared by modifying a phosphate dispersant with fatty alcohol polyoxyethylene ether by a hard inorganic substance with the Mohs hardness of more than 8.
On the basis of the scheme, the hard inorganic matters with the Mohs hardness of more than 8 in the super lubricant are one or a mixture of zirconia, tungsten carbide and boron carbide.
According to one embodiment of the present invention, the super-lubricant has a particle size D50 of the hard inorganic material having a mohs hardness of 8 or more of 80.0 to 130.0 nm.
According to one embodiment of the present invention, the super-lubricant has a mass concentration of the hard inorganic material having a mohs hardness of 8 or more of 15 to 25 wt%.
According to one embodiment of the present invention, the humectant is one or a mixture of two or more of glycerol, polyethylene glycol, sorbitol, and xylitol.
According to one embodiment of the invention, the bactericide is one or a mixture of two of isothiazolone and benzisothiazolinone.
According to one embodiment of the invention, the rust inhibitor is one of benzotriazole, triethanolamine borate and alkenyl succinate.
In another aspect, the present invention provides a method for preparing a water-based cutting fluid, comprising the steps of:
(1) Adding the fatty alcohol polyoxyethylene ether modified phosphate dispersant into deionized water, uniformly dispersing, adding the hard inorganic substance while stirring, continuously stirring to fully wet the surface of the hard inorganic substance, and uniformly dispersing in the mixed solution. Transferring the mixed solution into a sand mill, adopting yttrium stabilized zirconia beads with the diameter of 0.3 mm as a grinding medium, starting to circularly grind until the granularity D50 of the materials reaches 80.0-130.0 nm, ending grinding, and discharging to obtain the super-lubricant.
(2) Adding the super lubricant, the humectant, the bactericide and the antirust agent into deionized water, and uniformly stirring to obtain the super-lubricating water-based cutting fluid.
Compared with the prior art, the super-lubricating water-based cutting fluid disclosed by the invention has the following advantages that the super-lubricating water-based cutting fluid is used for processing metals or alloys and the like:
The super-lubricating water-based cutting fluid has simple formula composition, and adopts an aqueous dispersion liquid obtained by dispersing hard inorganic matters with the Mohs hardness of more than 8 by adopting a fatty alcohol polyoxyethylene ether modified phosphate dispersant as a lubricating component. The fatty alcohol polyoxyethylene ether modified phosphate dispersing agent has a strong chemical adsorption effect with the surface of metal or alloy, and can quickly drive hard inorganic particles to migrate to the surface of a processing part in the cutting processing process. The nano-scale hard inorganic particles play a role of a rolling bearing between a cutter and a workpiece in the cutting process, so that the friction resistance in cutting can be obviously reduced. The chemical adsorption effect of the fatty alcohol polyoxyethylene ether modified phosphate dispersant and the rolling bearing effect of the nanometer hard inorganic particles are comprehensively utilized, and excellent lubricating characteristics are obtained. In addition, the super-lubricating water-based cutting fluid has the advantages that the dosage of the surfactant is small, no obvious bubbles are generated in the processing process, so that the defoaming agent is not required to be added, the influence of the addition of the defoaming agent on the stability and the application performance of the system is avoided, and the production cost can be reduced.
